Slope has almost nothing to do with gravity. It's the height that counts. If you're ascend is 90 degrees or 70 degrees, the gravity will either speed up or slow the train down with 22 mph per second.
Yes, there is a small difference, but that's because a steeper slope has less tracklenght to cover, but that difference is very small.
